摘要/Abstract

摘要： 将细线偶极子的无限小缝隙模型运用于时域有限差分法计算中,采用已经进行频谱预估计的高斯脉冲源,用时域有限差分法给出了源点在不同位置时,细线偶极子天线输入阻抗的计算结果。并将中心激励的细线偶极子的输入阻抗的计算结果与矩量法(MoM)法计算结果进行了比较。

关键词: 细线天线, 天线输入阻抗, FDTD法, 激励源

Abstract: The infinitesimal gap mode of a thin-wire dipole antenna is used in FDTD Calculations. The antenna input impedance of thin-wire dipole antenna is calculated using performing deconvolution Gaussian type pulse source. The antenna input impedance's FDTD calculation result of the different excitation source location point's thin-wire dipole antena (center-fed dipole, 1/8-fed dipole, 1/4-fed dipole, and 31/8-fed dipole) are given and discussed. Furthermore, the antenna input impedance's FDTD calculation result of center-fedthin-wire dipole antenna agrees well with the MoM's calculation result.

Key words: thin-wire antenna, antenna input impedance, FDTD method, excitation source
